Softkeys Softkeys are shown along the bottom of the display. Some
softkeys have an immediate action, such as taking you to
another menu or initiating a measurement.
Other softkeys allow you to scroll through a list of choices,
such as channels or trigger operators. You can scroll through
the choices by pressing the softkey repeatedly or by using
the Entry knob. For some softkeys, you can use the Entry
knob to scroll through the choices. For channel lists, you can
always use the Select knob or Entry knob to scroll through
the choices.
Occasionally a softkey label is displayed with two or more
choices below it, one of which is highlighted. The highlighted
choice is the one that is currently active. Pressing the softkey
toggles the highlight to the other choice.
When several softkeys are displayed with a labeled bar over
them, it means that either the softkeys are related and/or that
the choices are mutually exclusive.
